  • Publication number: 20060079952
    Abstract: An embodiment of the invention provides a prosthesis delivery system comprising a delivery catheter having an expandable member and a prosthesis carried over the expandable member. The prosthesis includes a radially expandable scaffold section and at least two anchors extending axially from an end thereof, and means for capturing at least the anchors to prevent the anchors from divaricating from the expandable member as the catheter is advanced through a patient's vasculature.

  • Patent number: 7014644
    Abstract: A method and system for performing anastomosis uses an anvil to control and support a tissue site during an anastomosis procedure involving tissue bonding techniques such as tissue welding and adhesive tissue bonding. The anvil is particularly useful for supporting a wall of a coronary artery during attachment of a graft vessel in a coronary artery bypass graft procedure. The anvil is inserted into a pressurized or unpressurized target vessel and is pulled against an inner wall of the target vessel causing tenting of the thin tissue of the vessel wall. A graft vessel is then advanced to the anastomosis site and an end of the graft vessel is positioned adjacent an exterior of the target vessel. When tissue welding is used, a graft vessel fixture is positioned over the tissue surfaces to be welded in order to clamp the graft and target vessel tissue together. The tissue contacting surfaces of the anvil and/or graft vessel fixture are provided with one or more energy applying surfaces.

  • Patent number: 6994714
    Abstract: An anastomosis system and method uses an anvil to control and support a tissue site during an anastomosis procedure. The anvil is particularly useful for supporting a wall of a coronary artery during attachment of a graft vessel to the coronary artery because the wall of the coronary artery is very thin, difficult to grasp, and susceptible to tearing. In one method, the anvil is inserted into a pressurized or unpressurized target vessel and is pulled against an inner wall of the target vessel causing tenting of the thin tissue of the vessel wall. A graft vessel is then advanced to the anastomosis site and an end of the graft vessel is positioned adjacent and exterior of the target vessel. Staples are inserted through the tissue of the graft vessel and the target vessel by pivoting the arms of a staple holder towards the anvil. When the ends of the staples engage staple bending features on the anvil, the ends of the staples bend over securing the graft vessel and target vessel together.

  • Publication number: 20060025652
    Abstract: A cannula coupled to a displacement limiting coupling. The cannula includes at least one rigidizable segment and means for rigidizing the rigidizable segment. The displacement limiting coupling couples to an insertable device and aligns the axes of the insertable device and the cannula and establishes limits on the relative axial displacement between the cannula and the insertable device. The insertable device may have a steerable tip that maintains an overlap with the rigidizable segment due to the axial displacement limits.

  • Publication number: 20050267498
    Abstract: A device for everting an end of a hollow tissue structure may include a mandrel and a collar proximal to the mandrel. The mandrel may be elastomeric and deformable. At least one of the collar and the mandrel may be movable relative to the other. Deformation of the mandrel everts the end of the hollow tissue structure.

  • Patent number: 6966920
    Abstract: The anastomosis device according to the present invention is a one piece device for connecting a graft vessel to a target vessel without the use of conventional sutures. The anastomosis device includes a frame for receiving and holding the end of a graft vessel in an everted position and first and second spreading members configured to be inserted into an opening in the target vessel. The first and second spreading members are arranged substantially in a plane for insertion into an opening in a target vessel, and are moved away from one another to capture the edges of the opening in the target vessel securing the graft vessel to the target vessel. One version of the anastomosis device includes a plurality of linkages arranged in two rows for grasping opposite sides of an opening in the target vessel. A portion of the linkages fold outward to trap vessel walls on opposite sides of the opening in the target vessel.

  • Publication number: 20050251179
    Abstract: A method for performing anastomosis connects two tissue structures, such as blood vessels, end-to-end. At least two flaps may be created at the end of each tissue structure. Each flap of one tissue structure may be brought into contact with a corresponding flap of the other tissue structure. The corresponding flaps may be connected, such as by deploying one or more connectors therethrough.

  • Publication number: 20050234483
    Abstract: An anastomosis device may include an outer loop and an inner loop connected to and substantially concentric with the inner loop. The outer loop and the inner loop may be connected by at least one hinge. At least one of the outer loop and the inner loop may be movable relative to the other along an axis defined by at least one hinge.

  • Patent number: 6955679
    Abstract: An everter and threadthrough system useful for attaching a graft vessel to a anastomosis device which can be used to attach a graft vessel to a target vessel without the use of conventional sutures. The threadthrough system engages an end of the graft vessel and pulls the graft vessel through a deployment tool until a portion of the graft vessel extends beyond a distal end of the anastomosis device mounted on the deployment tool. The everter includes a spreading mechanism which expands the end of the graft vessel and folds the expanded end over the anastomosis device. In the case where the anastomosis device includes barbs, the everter can effect penetration of the graft vessel by the barbs. Once the graft vessel is everted over the anastomosis device, the deployment tool can be used to attach the graft vessel to a target vessel.
